davidhaas 32d9f25a6f Fixed up and made work a PBUF_REF type. Most of the code uses this now ... instead of PBUF_ROM. This addition allows support of copy-on-demand where the lower layers can call pbuf_unref() which tests for any PBUF_REF buffers and replaces them with PBUF_POOL buffers. This is now used everywhere. pbuf_unref() is called in ARP queueing and in the coldfire driver, which puts frames on a DMA queue and frees them later. Along with this change pbuf_free() now goes through the entire chain of buffers and tests all the ref counters, not just the first one. Generally now pbuf_ref_chain() should be called and not pbuf_ref(). This change was made because it is possible for the head of the pbuf chain to have a different count than the payload pbuf which might have been passed by the application.		2003-03-19 22:14:49 +00:00
